    Do not assume LHS of call is an ssa-name.
    
    gimple_range_fold makes an assumption that the LHS of a call is an
    ssa_name, which later in compilation may not be true.
    
            * gimple-range-fold.cc (fold_using_range::range_of_call): Ensure
            LHS is an SSA_NAME before invoking gimple_range_global.
